Donut had just been recovered with the other contestants by Two, who seemed to have finally recovered from his bedrotting. Now... how did everyone die again...
One had trapped him and made him give her some of Two's powers. But... he does remember she said he could be useful for something else. He barely remembered what happened, but... there was another number person there? One might've used him to erase them, actually. ...uhhh, he'll deal with that later. After Donut had just escaped from One, he was determined to tell everyone what One was doing. ...unfortunately he died before that could happen.
While everyone was trying to figure out what to do, he heard Bottle comment on how when he died, his jam was (insert color of user). ...That is probably the doing of One. He excused himself and ran up to the bathroom, grabbing a knife and testing the jam thing out. ...yep. It was indeed a different color. Okay, how does he deal with this. He needs to somehow get you out, that's for sure. ...but that can wait.
Donut stared at the mirror for a few seconds. He blinked. He BLINKED and then he opened his eyes, and- -HOLY SHI- He stared at you, now looking more ghostly in the mirror. Okay, chill, this happened with Four all the way back in BFB. And Four got out! ...should he... try and talk to you? Donut: "...hi...?"
